Who called from 8015751200

I got a call from this number.  I live in California and it is from Utah.  No message was left, so I called back from another number.  It is some sort of "Sutter Medical."

I keep getting calls every 30 seconds from this number.  It's fax line.  They have tied up my phone line at my business for two days now.  I've called the company, Sutter Medical in Utah.  They don't know what the problem is.  Ugh!!!!!!!!

I got a call from this number, and it was a nurse for Sutter Medical who was calling me about an appointment I made.
